Accurate debugging of the drum screen is fundamental to ensuring stable operation and optimal performance. This article will explore key points for debugging a drum screen.
Before debugging the drum screen, conduct a comprehensive equipment inspection. Ensure all components are properly installed and secure, especially critical parts like the drum, screen mesh, and motor. Check if the motor wiring is correct and if the grounding is good to ensure operator safety.
When starting the drum screen for the first time, begin with no-load debugging. Pay attention to the sound and vibration during operation. If abnormal noise or excessive vibration occurs, stop the machine immediately to check and troubleshoot.
After successful no-load debugging, proceed with load debugging. Gradually add a small amount of grain and observe the screening effect and processing capacity. Check if the screen mesh is working properly and if the grain is evenly distributed on the screen surface without blockages.
Based on the type of grain and screening requirements, observe whether impurities are effectively separated and if grains of different sizes are accurately graded. If the screening effect is not satisfactory, adjust the drum speed or screen mesh tension to achieve the best screening result.
For damp or sticky grains, reduce the speed to extend the grain's residence time on the screen mesh, improving screening accuracy. For dry, free-flowing grains, increase the speed to enhance screening efficiency.
During debugging, adjust the screen mesh tension device to change the tension. Also, check if the mesh aperture meets the screening requirements and replace the mesh if there is any deviation.
